hi,
I have put the mkisofs stuff together in a small shell script. You will be
asked for your server share, username, password, if you like another
keyboard layout and if the default boot should be local-system! Then a new
iso-image is generated.
It is for linux users for sure! Maybe someone else likes to use it...
regards, Moritz
